Kinematics Problem!

A cheetah can accelerate from rest to 26.0 m/s in 2.18 s. Assuming the acceleration is constant over the time interval, what is the magnitude of the acceleration of the cheetah?
ANSWER=1.91x10^1m/s^2

What is the distance traveled by the cheetah in these 2.18 s?
2.83x10^1m

A runner can accelerate from rest to 5.90 m/s in the same time, 2.18 s. What is the magnitude of the acceleration of the runner?
2.71m/s^2

****I DONT KNOW HOW TO DO THIS LAST PART BELOW PLEASE HELP!
By what factor is the cheetah's average acceleration magnitude greater than that of the runner?
 


Wouldn't that just be the runner's acceleration divided by the cheetah's?
